Lawn Sprinklers

What is a Smart Sprinkler or Smart Irrigation System and why do you need one? Let’s take a look at Rainmachine vs Rachio vs Skydrop.


Have you ever faced a situation in which you have just watered the lawn and in a few minutes it starts to rain? All the water and electricity that you spent on doing so seems like a waste. You can easily save on your utility bills only if you could predict the weather and knew how much water your plants need. Now you must be thinking, but how would I keep a tab of so many factors before irrigating my lawn? You need not! That’s the power of Smart Sprinklers and Irrigation Controllers.


Their brains (read controllers) are so well programmed and integrated with the internet that they can take these decisions for you. Instead of fixed timers, these systems make use of data acquired from sensors, weather forecasts and plant-care databases to decide how much water is needed and for what duration they need to run to provide the perfect moisture for the Tulips growing in your backyard.


All of these tasks are synchronized and controlled via mobile and web apps connected to the controller via Wi-Fi. The Smart Sprinkler Systems mentioned in this guide are EPA WaterSense Certified and are eligible for utility rebates in most of the communities. You need to contact your water authorities for more information on the same.


Now that you know you can save $$ on your utility bills and automate your irrigation at your fingertips, let me help you determine the best sprinkler controller for your use.

The Rainmachine comes in three variants each with the ability to control 8, 12 and 16 zones respectively.

Skydrop Sprinkler Controller




The Skydrop is not completely cloud dependent and can be manually controlled with the help of a jog-dial and a LCD screen. The controller can be used to monitor and manage watering from your computer, smartphone or tablet, Alexa, or Text Message.

The Skydrop comes as an 8 zone controller with an option of extending to 16 zones after purchasing the 8 zone expansion module. You also have an option of buying it along with Amazon Professional Installation service.

Skydrop’s Self-Regulating Controller customizes watering based on current hyper-local weather data to make sure your lawn and garden get exactly the water they need, across each unique zone. Having said that, the Skydrop does not support the addition of a PWS.

Skydrop gives you more ways to control the system and more options. You can connect to your Amazon Echo, Tap or Dot, Nest, Philips Hue and any other platform that works with IFTTT.

Rainmachine vs Rachio vs Skydrop – the winner is:


RainMachine for us has taken the edge over Rachio and Skydrop. The ability of the Rainmachine to be cloud independent and open source makes it the better sprinkler controller.
All the controllers are EPA WaterSense certified and are eligible for rebate. Rachio is for the ones who want to control their irrigation systems on the go, but we feel that there is a need for some kind of manual control.
The Skydrop is the most pocket friendly but lacks a few advanced features. Also, it is not very efficient to manually control the Skydrop with the help of a jog-dial.

Outdoor Enclosures for Smart Sprinkler Controllers

It is possible to mount the controllers outdoors. Just make sure that it is close to the Wi-Fi source and that there are not many walls present between the controller and the Wi-Fi source. The outdoor enclosures help to protect the controllers from humidity, rain, wind, and sun damage.

The Rachio and the Skydrop controllers have their company manufactured outdoor enclosures. Whereas, the Rainmachine works well with the Orbit Outdoor Enclosure.
